Mickelson shot five birdies and an eagle in his first round

Phil Mickelson shot a six-under 65 to share the lead in the first round of the Scottish Open at Loch Lomond.

The two-time Masters champion, who has been struggling with a wrist injury, had an eagle and five birdies.

Graeme Storm, Soren Hansen and Lee Westwood also shot 65, while Mikko Ilonen, Marcel Siem, Mark Foster and Christian Nilsson trail by a stroke.

Colin Montgomerie, who won the European Open on Sunday, birdied three of the first five holes but settled for a 69.

"Two under. I'd have taken it at the start of the day," he said.

"A four-iron at the 10th went awry and an eight-iron, the distance was wrong on the 12th. Not much wrong with the shots."

Mickelson's return from wrist trouble is a good sign with the Open Championship beginning in Carnoustie in a week.

"There is still pain. Every time you make contact, it stings," he said.

"But I know I can't damage it any further and so I'm not afraid to go for the shots."

After starting with two pars and a bogey, Mickelson eagled the par-five 13th and followed it up with a birdie.

He then birdied four of his last six holes, including an 18-foot putt at the seventh.
